Active and rinsing baths: bath preparation in the automotive industry
Extend the service life of chemical baths and rinsing baths with EnviroFALK ultrafiltration units. more
Activated carbon filter
Activated carbon filters are used in water treatment to adsorb organic compounds and to remove chlorine and chloramines. more
Bag filter
Bag filters are used in water treatment for separation of coarse particles or for final filtration if the solids concentration is very low. more
Industrial water treatment
Industrial water, also called service water, is used for cooling, production processes or rinsing in industrial applications. more
DI water system/DI water treatment plant
A DI water system or DI water treatment plant for the production of fully demineralised water (DI water). more
Dosing equipment
Dosing equipment, sometimes also called dosing station or dosing unit, is used for accurate dosing of products. more
Electrodeionisation
Electrodeionisation (EDI) is a technology which uses ion exchange resins and ion-selective membranes in combination with direct current to remove ions from the water. more
Electrolyte cleaning
EnviroFALK sets new standards for the separation of metal hydroxides using specially developed ultrafiltration units. more
Iron removal filter
Iron removal filters remove iron and manganese from the water. In general, they are filled with catalytic filter material and quartz gravel. more
Decarbonisation
Decarbonisation units remove hydrogen carbonates of calcium and magnesium (also called carbonate hardness, carbonate alkalinity, and temporary hardness) dissolved in the water. more
Demineralisation
Demineralised water is needed in many industrial and commercial processes as well as in hospitals, laboratories and medical technology. more
Fresh water treatment for glass processing companies
Demineralised fresh water or make-up water is often treated by ion exchange or reverse osmosis. more
Ion exchangers
Drinking water contains different salts in varying concentration. These salts consist of metal ions (cations) and an acid residue (anions). more
Cartridge filters
Cartridge filters, also called candle filters or fine filters, are non-backwashable protective filters. more
Boiler feed water
Consistently high boiler feed water quality using EnviroFALK water treatment equipment. more
Sand filters
Sand or gravel filters remove undissolved solids (particles) from water or from process fluids. more
Closed loop/water recirculation technology for the glass industry
EnviroFALK pure water recirculation systems produce deionised water of a consistently high quality, thus ensuring a high degree of process reliability. more
Cooling water treatment
EnviroFALK cooling water treatment units ensure safe operation of cooling systems. Cooling systems need large amounts of water in their circuit and for evaporation. more
Laboratory water treatment
EnviroFALK makes water treatment systems for the production of laboratory water. This is also referred to as laboratory water treatment, as pure water of different qualities and quantities is used for general as well as specific laboratory applications. more
Multi-media filters
Multi-media filters or multilayer filters remove even the most minute dirt particles from the water by in-depth filtration and adsorption. more
Metal cleaning
Typical tasks performed by metal-processing companies include drilling, milling, turning and welding, which at first sight may not have much to do with water treatment. more
Microfiltration
Microfiltration (MF) is used to remove all solids from the water that are larger than the membrane pore size. more
Mobile clean room
To prevent particles from entering the water treatment units during the production process, the entire process is carried out in a mobile clean room, under low-particle conditions if necessary. more
Nanofiltration
Nanofiltration (NF) is used for partial softening and reduction of turbidity and discolouration of surface water. more
Process water
Industrial processes often require specially conditioned water or steam, referred to by specialists as process water. more
Cleaning baths – bath preparation
Between the various processing stages components need to be cleaned repeatedly along the entire production chain, and the cleaning results are only as good as the quality of the bath. more
Pure water circulation system
Do you want to reduce your operating costs in the field of water and energy? EnviroFALK pure water recirculation systems are the solution. more
Grinding water treatment/drilling water treatment for the glass industry
The newly developed EnviroFALK grinding water treatment system sets new standards. Cost-cutting and safe to use. more
Protective filters
Protective filters protect piping systems and downstream units from coarse and fine dirt particles. more
Rinse water treatment
In open systems, rinse water is rejected after use. One way of keeping the cost of fresh water, wastewater as well as any heating energy down, is to reduce the volume of water used. more
Ultrafiltration
Ultrafiltration (UF) is a process where water is filtered by a polymeric membrane with a very small pore size. more
Reverse osmosis
Reverse osmosis is based on the principle of osmosis, which can be observed, e.g., in burst cherries after a summer rain. more
DI water
DI water means deionised water. Deionised water is also called (totally) demineralised water or desalinated water. more
Washing water and rinsing water for the glass industry
EnviroFALK water treatment units supply glass processing companies with washing and rinsing water of consistently high quality. more
Water treatment unit
Due to scarce resources, impurities in raw or drinking water and consistently increasing requirements, most industrial processes need a water treatment unit. more
Water softening
During water softening by ion exchange, cation exchange resins are used to replace cations such as calcium and magnesium ions, which are responsible for water hardness, with sodium ions. more
